Rubber foot for a heatable metal device

A heatable metal device with at least one hole in its bottom side, wherein the metal device comprises at least one rubber foot inserted or insertable into the at least one hole in the bottom side of said metal device, wherein an upper side of the rubber foot facing toward the bottom side of said metal device is concave and includes an inner curvature and an outer curvature, wherein the inner curvature has a smaller radius of curvature than the outer curvature, and wherein each of the inner curvature and the outer curvature are concave.

A rubber foot for supporting a heatable metal device, said rubber foot comprising:

• a head having a concave upper side, a cylindrical shaft extending upward from said upper side of the head, and a first ring extending circumferentially about said shaft and being interrupted by at least one recess arranged in said first ring, said at least one recess defining an evacuation channel that permits air to pass as the rubber foot is inserted into a hole in an underside surface of said heatable metal device in order to ease insertion therein, wherein the concave upper side includes an inner curvature and an outer curvature, and wherein the inner curvature has a smaller radius of curvature than the outer curvature.
